AUTOMATIC PRESSURE-ROLL RELEASE FOR CLOTHES-WBINGEBS.

. citizen of the United States, residing at Washington, in the Districtof Columbia, have invented certain new and useful Improvements inAutomatic Pressure-Roll Releases for Clothes-Wringers, of WhlCh thefollowing is a specification, reference being had therein to theaccompanying drawing.

This invention relates to certain new and useful improvements in anautomatic pressure roll release for clothes wringers, and the object ofthe invention is to provide means for automatically releasing thepressure on the pressure rolls instantaneously without allowing the topbar to become displaced from the wringer frame.

Another object of my invention is to provide a clothes wringer havingmovably mounted retaining members cooperating with the movably mountedtop bar in such amanner that the top bar can be held in predeterminedposition so that the proper pressure can be exerted on the pressurerolls and allowed to move vertically in order to release said pressuremeans without becoming detached from the wringer frame.

Another and furtherobject of the invention is to provide novel means foroperating the movably mounted members for holding the movably mountedtop bar in position within the wrin er frame which are in the form of anangular'lever pivotally mounted on the wringer frame having portionsarranged in the path of travel of one of the pressure roll shafts, andconnected at the opposite ends to the movably mounted members so thatwhen the pressure rolls are separated, the movable members will beshifted in order to release the pressure on the pressure rolls.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings,

Figure 1 is a side elevation partly in section of a clothes wringershowing the application of my improved construction of pressurerollreleasing device thereto; and

Fig. 2 is an end elevation of the same.

Like numerals of reference refer to like parts in the several figures ofthe drawing.

In carrying out my invention, I employ a wringer of the ordinaryconstruction com- Specification. of Letters Patent.

posed of a frame 1 having slotted side bars in which are mountedsuperposed bearings carrying pressure roll shafts 2 and 3, the upperbearings having spring supports on which are mounted pressure springs 4engaged by bearing plates 5 carried by a pressure bar 6. The bearingplates 5 of the pressure bar 6 are adapted to be engaged by pressurescrews 7 mounted in threaded boxes 8 of the movably mounted top bar 9which is 'slidably mounted within the slotted side bars of the wringerframe.

Secured across the slots of the side bars of the wringer frame at theirupper ends are movably mounted retaining members 10 in the form ofplates having guide slots 11 through which guide "screws or pins 12 areadapted to pass for holding said plates in position on the 'wringerframe in such a manner that the plates are free to move transversely.The plates are provided with notches 13 adapted to receive theprojecting studs 14L carried by the ends of the movably mounted top bar9 so as ,to allow the top bar to move vertically within the wringerframe when the notches 13 are brought into vertical alinement with thestuds 14, the lower edge of saidplate being normally held in a planeabove the studs 14 as shown in Fig. 2 so as to hold the movably mountedtop bar in predetermined position within the wrmger frame in order toallow the pressure screws to be adjusted so that the desired pressure onthe pressure rolls can be obtained.

In order to provide means for automatically shifting the retainingmembers '10 transversely of the wringer frame so as to bring the notches13 thereof into vertical alinement with the studs 14 of the movablymounted top bar, I pivotally mount on the side bars of the wringer frameangular levers 15 which are slidably connected at 16 at their upper endsto the retaining members 10, and are provided with portions 17 at theirlower ends arranged in the path of travel of the pressure roll shaft 3so that when the pressure roll shaft is mor'ed by the separation of thepressure rolls. the portions is prevented from becoming detached fromthe wringer frame.

From the foregoing description it will be seen that I have provided aclothes wringer with an automatic pressure roll release composed of apair of retaining members arranged to hold a movably mounted top bar inpredetermined position within the wringer frame, and to allow said topbar to move acertain distance to release the pressure means, saidretaining members being shifted into position to release the top bar bylevers actuated by the vertical movement of one of the pressure rolls.

1 claim:
